Store and Office Air Conditioning Systems and District Heating & Cooling Systems |
|
| |
With the aim of creating a comfortable environment in facilities such as stores, office buildings, hotels and hospitals,
Hitachi Appliances has developed System Free, a packaged air conditioner that enables systems to be designed
according to customer needs. We have also commercialized Hi-Inverter IVX, which achieves industry-leading high
efficiency. In recognition of its excellent energy-saving function, this product was awarded the Minister Prize of
Economic, Trade and Industry at the 2005 (16th) Energy Conservation Grand Prize for excellent energy
conservation equipment.
Furthermore, we are at the forefront of delivering one-of-a-kind technologies through offering products such as
an ice storage system using nighttime electricity, a chiller unit and compact refrigerating eguipment that employs
scroll and screw compressors, a highly efficient absorption chiller and a large centrifugal chiller for district heating
and cooling systems. |

The Shirokumakun room air conditioner equipped with a double
accelerator system realizes high efficiency through PAM (pulse
amplitude modulation) control technology and software technology
enabling increased energy efficiency and temperature and humidity
control, for which this product subsequently received the Chairman
Prize of the Energy Conservation Center, Japan at the 2004 (15th)
Energy Conservation Grand Prize for excellent energy conservation
equipment. Additionally, we are contributing to creating comfortable
and healthy living environments through launching an air conditioner
in 2005 equipped with "Nano & Plasma" technologies that eliminate
pollen by approximately 99%*.

Safe and Reliable Food |
|
| |
| In line with the U.S. food hygiene control system based on HACCP
standards being introduced at food processing plants, Hitachi
Appliances develops and supplies low-temperature control systems
to meet the needs of various facilities. Additionally, our low control
technology is actively employed in many other areas such as food
storage as well as amusement facilities that include ice skating rinks
and artificial ski slopes. |
